Immediate Regrafting of the Split Thickness Skin Graft Donor Site Assists Healing
© 2017 The Authors. Published by Wolters Kluwer Health, Inc. Background: Delayed or even lack of healing of a split-thickness skin graft (STSG) donor site is a potential problem with elderly patients or those with poor wound healing capabilities. A proactive solution that may minimize this risk is to regraft that donor site using otherwise discarded skin graft remnants. Methods: A prospective, nonrandomized, consecutive study was designed to compare the time to healing of the commonly used anterior thigh STSG donor site in patients who had routine dressings (n = 113) versus those with comorbidities known to adversely affect wound healing and had planned regrafting (n = 204). Those comorbidities included age (≥65 years), diabetes mellitus, peripheral vascular disease, chronic renal disease, and chronic steroid use. Results: The average number of comorbidities in the regrafted subgroup versus those not regrafted was 1.41 and 0.31, respectively. This was considered to be a significant difference (P < 0.0001) confirming the validity in predicting patients at risk for adverse donor-site healing that would benefit by regrafting. The mean time required for donor-site reepithelialization of those regrafted was 17.2 days compared with 17.8 days for those not regrafted (P = 0.2395), which was not significantly different. Conclusions: Regrafting the STSG donor site of patients with known comorbidities, that is, those expected to have delayed healing in general, had a mean time to reepithelialization comparable with conventionally treated individuals. This was considered a direct consequence of recycling rather than discarding any excess skin graft materials when so indicated and can be a proactive solution to a potentially cumbersome dilemma.
